GABBONATOR.

Specification of Letters Patent.

Patente Jan. 27, 1914.

Application led January 10, 1918.4 Serial No. 741,217.

To all whom 'it may concern Be it known that I, DAVID Enrr, a citlzen of the United States, and a resident of Westport, in the county of Essex and State of New York, have invented a new and lmproved Carbonator, of which the followmg is a full, clear, and exactdescription.

his invention relates to an apparatus for carbonating and dispensing beverages, and has for its object an inexpensive, simple, compact and reliable device for producing a rapid and perfect saturation of the liquid with carbon-dioxid. The carbon-dioxid and Wat-er are forced to pass together through a continuous passage provided with a plurality of perforated and whirl-forming dilaphragms toward the dispensing nozzle.

The invention consists of the construction and combination of parts to be more fully described hereinafter and fully -set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this speciication, in which like characters indicate parts in all the views and in wh1ch:

Figure 1 is an elevated longitudinal section through the member having t-he continuous passage; Fig. 2 is a section on -li'ne 2 2, Fig.v1; Fig. 3 is a plan view of a dlaphragm provided in the continuous passage; and Fig. 4 is a section on the'line 4 4, Fig. 3.

Referring to the drawings, represents a casing or member having a continuous passage. The continuous passage is formed of a series of horizontal superposed passages 11 interconnected alternately by means of vertical passages 12 angular in shape, so that the liquid passing from one horizontal passage to the following one has not a smooth curved passage but an angular one, thus increasing. the resistance to the passage of the liquid and forcing it to partly break up by expanding the same.

he casing lO is head 13 positioned on the upper end of the casing at the beginning of Athe continuous passage of the casing. The head 13 is at one side provided with superposed inlets of water and gas, 14 and 15 respectively. The pipe 16. leading the water to the inlet 14, is placed above the pipe 17 leading the gas to the inlet of the head 13. Check valves 18 provided with an inlet` and 19 areprovided on the ipes 16 and 17, allowing, only the Water and) gas to iiow inward into the head 13, but preventing the reverse.

Theinlet proper of the continuous sage 11 formed 1n the head 13 is provided h an inverted, cu -sha ed diaphragm 20 projecting with the ulgeg port-ion into the' head 13. The diaphragm is provided with perforations 37 in its bulged portion jecting into the head, and also provided with radial slits 38 converging toward the center of the diaphragm, so that the water and gas enter through the pipes 16 and 17 into the head, are orced to pass through the perforations of the diaphragm and through the slits and, due to the construction of the slits the in entering the conti uous passage 1l.

Due to the superposed passage of the inlets of water and gas the lm of water formed above the gas naturally tends to iow downward, while the gas tends to rise, and, similarly, the water and gas bein liquid is made to whirl thrown against the walls of the head 13 and across the perforations and the slits of the diaphragm breaksy up into finely divided streams having an enlarged surface for contact with the gas present in the head coming through the inlet pipe 17. IUnder the pressure of the iniow water and gas the water passing through the diaphragm 20v flows into the passage and also rotates, due to the creation of the Whirl of the slits formed in the diaphragm 20.

The water flowing through the assages l coming in contact with the vertical passages 12, a's above stated, again breaks up and allows a better intermingling between the gas and the water present in the passage. That is, the area of contact of the liquid and the gas present is increased in those vertical passages, thus allowing a better contact and, consequently, a better saturation of the water with the gas present. To form a better intermingling and create alcontinuous rotation of the flowing water, the passages 11 are` provided with diaphragms 2l provided withperforations 39 and positioned near the opposite ends of the consecutive horizontal passages. phragms 21 are also provided^ with radial slits 40 convergin toward each vother and angular-ly dispose so as to create a whirl The diawhen the water is passed throu h the slits. Again, due to the assage o the water through the perforations and s11ts,the water is divided into fine streams, thereby forming a large area exposed to the contact of the gas present, and, consequently, permittin a good saturation of the owmg water wit the gas present in the (passage. T he number of passages provide on the dlaphragms and the number of vertical connections 12 may be increased or decreased accordin to the size and the degree of saturation esired. The outlet of the casing 10, provided at the end of the continuous passage, is connected to a storage tank 22 1n which the water saturated with the carbon-dioxid is stored and from where it can be drawn through the pipe 23 leading to the dispensing nozzles. The stora e tank 22 is also' provlded with a pipe 24 eading to a pressure gage 25 indicating the pressure in vthe storage tank and from which it can be seen if the pressure should be increased or decreased. The 'casing 10 is also provided with a valve 26, positioned on one of the vertical passage members 12, forpermitting the blowing out of the accumulated gas in the continuous passage of the casing.

When the carbon-dioxid and water iow through pipes 16 and 17 into the head 13, the water, flowing above the gas and being thrown against the wall of the head 13 and the cup-shaped diaphragm 20, breaks up and intermingles with the inflowing gas, and then, due to the perforation provided in the diaphragm, and also the radial curved slits in the diaphragm, the water is forced to whirl and break up into fine streams, thereby exposing a large surface to the contact of the gas present and simivlarly owing through the passage. And, again, as above described, by this continuous division of water and gas into ine streams by means of diaphragms provided in the continuous passage, a large varea of the fiowing liquid is continuously exposed to the gas present and thereby a perfect saturation of the liquid and gas is obtained. The saturated liquid accumulated in the storage-tank from which it is dispensed by means of the pipes 23 may accumulate on the upper portion a certain amount of carbon-dioxid, particularly when the pressure is reduced, and, consequently, if the pres-` sure is increased as we assumethat the temperature remams constant this accumulated carbon-dioxid will necessarily dlssolve when the pressure is reached which it had origi ually; also, the excess of carbon-dioxid accumulated in the top of the storage tank may be disposed of by means of a cock provided in the pipe 24, not shown in the drawing.

While the drawing shows the easing 10 cast in a single piece, the same. may be formed of a series of pipes soldered or otherwise secured to the vertical passages 12 similarly made of separate pieces or formed of a single piece with the pipes soldered to it. Diaphragme may be secured inthe passage 11 by means of solder or any other suitable way. The angularity of the'blades forming the diaphragm may vary, and the.

size of the slit formed between may also vary accordingly. The ,slits may be curved, as shown in Fig. 2, or straight as shown in Fig. 3, according to the amount of whirl it is desired to create in the continuous passage of the member 10. it may also be remarked that the diaphragms positioned in the passage create behind this assage a slight depression, thereby allo g an expansion of the liquid passing through the diaphragm and, conse uently, obtaining a perfect intermingling o the gas and water by exposing much surface to contact.

Having thus described my invention, what l claim and desire to secure-by Letters Patent is:
